Gram-negative rods, 0.5-1.0 x 1.0-3.0 µm with rounded ends. Usually motile by
means of peritrichous flagella. Occur alone, in pairs, sometimes in chains.

S-type colonies. Growth temperature 36 ºC. Facultatively anaerobic.
Subsp. dadantii was isolated from soft rot and wilt of Pelargonium capitatum, Ananas comosus, Dianthus spp., Euphorbia
pulcherrima, Ipomoea batatas, Musa spp., Philodendron spp., Saintpaulia ionantha and Zea mays.
Subsp. dieffenbachiae was isolated from soft rot and wilt of Dieffenbachia spp., Lycopersicon esculentum & Musa spp.

Subsp. dieffenbachiae was isolated from soft rot and wilt of Dieffenbachia spp., Lycopersicon esculentum & Musa spp.
Cause vascular wilts or soft rots on a range of host plants.
